While it’s almost an unspoken rule that every available moment of a Chicago summer should be spent frolicking outdoors, the Music Box Theatre’s lineup for its third annual Summer Music Film Festival makes a strong case for ditching the shades and risking a vitamin D deficiency. Presented over five days and nights (June 28 to July 2) in conjunction with Greg Kot and Jim DeRogatis’ disc dissection, Sound Opinions, the fest opens with an intimate look at the life of The Band’s charming drummer, the late Levon Helm. Ain’t In It For My Health: A Film About Levon Helm focuses less on the legendary friction that severed the group and more on Helm’s resurgence after cancer. Appointment viewing for anyone who missed out on Helm’s star-studded Midnight Ramble sessions in his Woodstock home/studio.

Keanu Reeves’ Bill And Ted’s Excellent Adventure sidekick Alex Winter brings his Napster documentary, Downloaded, to the fest along with the inaugural installment of the early ’90s bodacious buddy franchise. U2’s stylistic eye, Anton Corbijn, steps out from behind the camera as the subject of Anton Corbijn Inside Outwhile two train tours separated by decades (but not ideals) pull into the station with The Grateful Dead, Janis Joplin, and Delaney & Bonnie & Friends (Festival Express) and Edward Sharpe & The Magnetic Zeros and Mumford And Sons (Big Easy Express).
